EDWIN E. MILLER, OF ROCHESTER, MICHIGAN.

AGETYLENE-GAS GENERATOR.

To all whom it may concern:

Be it known that I, EDWIN E. MILLER, a

' citizen of the United. States, residing at Rochester, county ofOakland, State of Michigan, have invented a certain new and usefulImprovement in Acetylene-Gas Gen erators, and declare the following tobe a full, clear, and exact description ofthe same, such as will enableothers skilled in the art to which it pertains to make. and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to acetylene gas generators.

It has for its object an improved device for feeding the carbid into thegenerating tank.

In the drawings :-Figure 1, is an eleva tion, partly in section, of thetanks. Fig. 2, is an elevation, partly in section, showing in detail themouth of the carbid hopper. Fig. 3, is an enlarged detail of the sweepactuator.

1 is a generating tank, filled, or partially filled, with water.

4 is a cap at the upper end of the tank 1. At the apex of the cap 4 is ahopper-like receptacle 6, closed at its upper end by a movable cover 7To feed the carbid properly into the generator, I make a carbid holder 6funnel form, with a curved hanging bottom or receptacle 30, withopenings or mouths 132, 133, through which the carbid is ejected by ashoe 131; this shoe is located above the upper surface of the bottom 30,and is connected to a sweep 31, which is pivotally connected to aswinging arm 32, pivoted within the generating tank and to the bottomend of the carbid hopper 6. The sweep 31 is pivoted to the end of thearm 32, to which is also pivoted a link 33 which at its lower end isconnected to a link 34, which extends upward and emerges from the tankthrough a sleeve 134. The lower end of the sleeve 134 dips below thesurfaceof the water in the generating tank. The sweep is provided with ashoe 131, and will be actuated to crowd a load of carbid off from thebottom 30, when the gasometer bell has fallen in consequence of thedischarge of the gases contained therein.

the link 34 terminates with screw threads upon which are run twoabutment pieces or arms 35 and 36, both of which are adjustable alongthe link, both with respect to the link 34 and to each other, providingmeans whereby the movement of the shoe 131 is adjustable to feed more orless carbid.

Upon the side of the outer shell 2 is secured a post or arm 37, uponwhich there is pivoted a lever 38 provided with rolls 39 and 40.

42 is a weight upon the outer end of a link 42, which latter isconnected at the end opposite to the weight to the link 38, so as to beangularly adjustable relative thereto.

Upon the side of the gasometer-bell 20, adj acent to the post 37, issecured a curved finger 41, that normally reaches over the roll 40. Asthe gas escapes from the bell 20, and the bell 20 begins to fall, thecurved finger 41 engages over the roll 40 on the lever 38 causing thisend of the lever to swing into the curve of the fin ger, moving theweight 42 past the center of gravity, causing it to descend until thelever strikes the stop 45. In this movement the lower end of the leverwith the roll 39 travels along the arm or abutment 36, and from there tothe abutment 35, and lifts the link 34. The lifting of the link 34swings the lever 32 and pulls sweep 31 and shoe 131 across the bottom30, and forces the carbid through the opening 132. The carbid drops inthe water and forms gas, and raises bell 20, and causes the lower partof the curved finger 41 to engage roll 40, raises the weight 42 past thecenter of gravity, and causes the roll 39 to reverse the movement of theabutment 35, link 34, lever 32, retracting sweep 31, and shoe 131, topoint of beginning; at the same time another supply of carbid is pushedout of opening 133.

lVhat I claim is 1. An acetylene generating device, having a rising andfalling bell, a generator having a carbid feeding device, a receptaclefor the carbid, a sweep provided with a shoe adapted to feed the carbid,a link connected with sald sweep so as to actuate the same, movable armsupon said link whereby the movement of the same may be regulated, acurved finger adapted to be operated by the movement of the gas bell,and a weighted lever adapted to engage the arms upon said link and to beoperated by said curved finger, substantially bell and Weight operatesthe feeding shoe,
